CRUDE-OEL ELEVATOR.

Application filed November 20, 1923, Serial No. 675,967.

To all whom t may concern.'

Be it known that l, Estimo CORTS, citizen of the United Mexican States,residing at Mexico city, Mexico, have invented certain new and usefulImprovements in Crude- Oil Elevators, ot which the following 1s aspecication.

This invention relates to an elevator for raising crude oil atatmospheric temperature out oi' tanks. The adhesiveness of the crude oilis taken advantage of by conducting the endless belt ot the elevatorthrough the oil and against an adjustable scraper extending into agutter for collecting the oil adhering to the belt.

The endless belt is trained over two pulleys one of which is adj ustablymounted in a bearing and the other permanently mounted in a bea-ring,both bea-rings being {iXed to a swinging trame resting on top of a hori-Zontal frame.

The object of the invention is to extract crude oil from deposits ortanks without necessitating the use ot a pump or the heating of thecrude oil.

Fig. 1 is a side view ot the elevator.

Fig. 2 is an end view of same.

On the top of tank (l) is mounted a horizontal trarne ot I-beams (2) forthe general support of the elevator. Near one end ot the tank an axle(3), fastened transversely to the elevator 'frame (4) also made of I-beams, may turn in the bearings (5).

Two diagonal struts (6), pivoted to clamps (7) sliding on the frames and(2), keep the frame (4:) adjusted with relation to the horizontal frame(2) according to the inclination required for the elevator.

At one end of elevator trame (4), the driving shaft (8) mounted in thebearings (9) supports a transmission pulley (10) and the upper elevatorpulley (ll), over which latter passes the endless belt (l2) as also overthe lower elevator pulley (13), the shaft (lil) of which is adjusted bytwo stretcher rods (16) in the elongated loop bearings (15) attached tothe other end of frame A tray (17) fastened to the hangers (i8) issuspended from brackets (19) while the lower ends ot the hangers areforced toward the elevator belt by the action of spiral springs (20) onbrackets (21).

The tray extends into a gutter or pipe (2Q) by which the crude oil isdischarged.

As the elevator belt should be driven at slow speed a reducing beltsystem (28) transmits motion from the motor (24) to the pulley (10).

The elevator belt may ot course be made of leather, metal or any otherflexible material or may be substituted by a chain.

The pulleys over which the elevator belt passes may be large, orsubstituted by two smaller pulleys at the bottom of tank (l) in order toenlarge and lower the extension of the belt, which mustbe submerged inthe crude oil. This may be advisable in order to enable the extractionot the oil from the tank when the latter is almost empty.

It is of course understood that the crude oil adhering to the belt isscraped ott due to the resistance ot the tray edge being` held againstthe moving belt, and is thus collected in the tray.

Having thus described my invention what l claim is:

1. A crude oil elevator comprising a swinging frame, pulleys in each endthereof, an endless belt trained over said pulleys, stretching means forsaid belt, means 'tor adjusting said frame at an inclination, a scrapertray yieldingly held against the endless belt, and means for drivingsaid belt at slow speed.

2. A crude oil elevator, comprising a tiltable trame; an endless beltmounted therein; means for retaining said trame in adjusted tiltedposition; means for driving said belt; and means for removing from saidbelt the oil adhering thereto.

3. A crude oil elevator, comprising a tiltable frame; an endless beltmounted therein; a supporting :trame with which the tiltable frame ispivotally connected; retaining members pivotally related at oppositeends to the tiltable and supporting frames to hold the former inadjusted tilted position; means for driving said belt; and means forremoving from said belt the oil adhering thereto.

4. A crude oil elevator, comprising a supporting trame; a pair ofalining bearings mounted thereon; a tiltable frame; an endless beltmounted in the latter frame; a horizontal axle secured intermediate itsends to the tiltable frame and journaled at its ends in said bearings,thereby to enable a swinging movement ot the tiltable frame in avertical plane; means for retaining said tiltable trame in adjust-edtilted position; means for driving said belt; and means for removingfrom said belt the oil adhering thereto.

5. A crude oil elevator, comprising a supporting frame and a tiltablefra-mc each consisting ofY a.y pair of spaced, parallel beams;

an endless belt mounted in the tiltable.

frame; a pair of clamps slidably mounted on the beams of each frame; apair of diagonal struts pivotally connected at opposite ends to saidpairs of clamps to retain the tiltable frame in adjusted tiltedposition; means for driving said belt; and means for removing from saidbelt the oil adhering thereto.

6. A crude oil elevator, comprising asupporting frame and a tiltableframe each consisting of a pairof spaced, parallel beams; an endlessbelt mounted in thev tiltable frame; a pair of alining bearings mountedon the beams of the supporting frame; a horizontal axle securedintermediate its ends to the beams of the tiltable frame and journaledat its ends in said bearings, thereby to enable a swinging movement ofsaid tiltable frame in a vertical plane; a pair of clamps slidablymounted on the beams of each frame;'a pair of diagonal struts pivotallyconnected at opposite ends to saidv pairs of clamps to retain thetiltable frame in adjusted tilted position; means for driving said belt;and means for removing fromsaid belt the oil adhering thereto.

7. A crude oil elevator, comprising a vertical frame embodying a pair ofspaced, longit-udinal beams; an endless belt mounted therein; supportingmeans forsaid frame; means for drivmgsaidbelt; a pair of bracketsattached to the upper portions of said beams; a pair of dependinghangers pivot-ed to said brackets; a scraper disposed between andconnected to said hangers to remove from the belt the oil adheringthereto; a pair of brackets attached to said beams below the first-namedbrackets and with which the lower ends of the hangers are looselyengaged and v springs mounted on thek lower brackets andy bearingagainst said lower hangerends to force the scraper yieldingly againstthe belt. 1 v

8. A, crude oil elevator, comprising a vertical fra-me embodying a pairof spaced, longitudinal beams; upper and lower pairs of bearingsattached tosaid beams; the lower bearings being-elongated; upper and.lowerpulley shafts mounted in-V said bearings, a pulley on each shaft;anendless belt passing aroundsaid pulleys; driving means connected tothe upper shaft; a pair of.y adjustable stretcher rods connectedintermediate their ends to-said beams and at their lower ends tothelowerpulley shaft, to IIlOVethe latter and its pulley upward or downward toadjust the tension ofk the belt; and a. scraper for removing from theupper portion of said belt the oil adhering thereto.
